“…In 2000-2009, there was a trend towards an increase in sanitary-bacteriological indicators in water in the area of discharge of "decontaminated" wastewater from the Baikal Pulp and Paper Mill (Shchetinina et al, 2013). In view of the deteriorating sanitary situation, the authors of the paper conducted studies on the diversity and antibiotic resistance of bacteria isolated from water in the most anthropogenically influenced areas of the lake.…”

The analysis of sanitary-bacteriological assessment of water quality in the littoral and pelagic zones of Lake Baikal for the whole period of microbiological studies of the ecosystem was carried out. It was established that such studies were single in the last century and only from the end of the century they began to be carried out all over the lake, and now they are carried out annually in the spring, summer and autumn periods over the whole water area of Lake Baikal and in the estuaries of large tributaries. The water quality of the lake was assessed and unfavourable areas in the littoral zone were identified for exceeding SanPiN standards. In 2021-2023, wastewater samples were taken after the treatment facilities in the Slyudyanka and Severobaikalsk towns, low efficiency of disinfection and inflow of opportunistic and pathogenic bacteria into Lake Baikal (bacterial pollution) were revealed. The scheme and periodicity of sanitary-bacteriological monitoring of the Lake Baikal ecosystem is proposed.

“…In the littoral zone of the same wastewater discharge area, there was contamination with hepatitis A viruses and rotaviruses. In deep areas, there were no anthroponotic viruses and FIB (Maksimov et al, 2003;Shchetinina et al, 2013). For 47 years of the BPPM operation, the waters of the Southern Baikal have been subject to constant anthropogenic load in the form of the BPPM wastewaters as well as domestic sewage of the Baikalsk town, which is fed to the treatment facilities until now.…”

“…For 47 years of the BPPM operation, the waters of the Southern Baikal have been subject to constant anthropogenic load in the form of the BPPM wastewaters as well as domestic sewage of the Baikalsk town, which is fed to the treatment facilities until now. From 2000 to 2009, there was an increase in the sanitary-bacteriological indicators near the BPPM wastewater discharge (Shchetinina et al, 2013). The deterioration of the sanitary situation initiated studies of the diversity and antibiotic resistance of bacteria isolated from the lake areas with a high anthropogenic impact (Shchetinina and Maksimov, 1999;Verkhozina, 2003;Savilov et al, 2008).…”

The article provides information about the sanitary-bacteriological studies conducted in the water area of Lake Baikal. We show the data on the long-term observations of the spread and abundance of fecal indicator bacteria and potentially pathogenic bacteria in the pelagic and littoral waters of the lake. We also present a review of the standards and methods for the sanitary-bacteriological water quality worldwide, techniques for detecting fecal indicator bacteria, including those specific for human microbiota, methods for microbial source tracking, as well as studies of the spread and retaining of fecal indicator bacteria in various ecotopes, such as bottom sediments and biofilms. For the sanitarybacteriological monitoring of Lake Baikal, we propose an integrated approach based on the application of modern techniques that correspond to world practice. This approach would allow identification of the sanitary adverse sites and more reliable and standardized assessment of the Baikal water quality.
